BRAKE-BEAM.

SPECIFICATION forming part of Letters Patent N0. 789,998, datedMay 16,1905.

' Application filed January 9, 1905. Serial No. 240,254.

To all whom it may 0071067711.

Be it known that I,JOHN F. OCoNNoR, a citizen of the United States,residing at 267 Ontario street, Chicago, Illinois, have invented acertain new and useful Improvement in Brake- Beams, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which I Figure 1 is an end elevational view,partly in section, of my improved brake-beam. Fig. 2 is a sideelevational View of a brake-head. Fig. 3 is a-vertical sectional view onthe line 3 3 of Fig. 1, and Fig. 4 is a horizontal sectional view on theline 4: 4 of Fig. 1. 1

This invention relates to a new and useful improvement in brake-beams,the object being to provide an adjustable head on the brakebeam whichwill accommodate the throw of the beam, the said head being formedwithfriction devices, whereby it is held in its adjusted positions, andalso provided with a bearing-point to take the strain off of thefriction devices.

With these objects in view the invention consists in the construction,arrangement, and combination of the several parts, all as will behereinafter described, and afterward pointed out in the claims.

In the drawings, 1 indicates a brake-beam,

shown as an ordinary deck-beam; but other forms may be employed. 2 isthe brake-head, having the usual securing-lugs for the remov ablebrake-shoes. This brake-head is provided with rearwardly extending webs3, which are recessed, said webs being formed with friction flanges orshoes 4 on each side of the recess, which friction-flanges are designedto'be received in a two-part keeper 5, secured to the brake-beam. Thiskeeper, as shown in Fig. 3, is composed of two parts and consists,essentially, of flanges for thereception of the securingrivet,one part 6of the keeper forming a circular portion about which the friction-shoes4 may move while said friction-shoes are held in position by overhangingflanges7. The parts of this keeper embrace the flange of the brake-beam,as shown in Fig. 1, and at their point of division in front of the beamthe said parts of the keeper are provided with flanges 8, (see Fig. 4,)which flanges are arranged on each side of a fin or web 9, formed at theforward end of the recess in the brake-head. This fin or web 9 isprovided with oppositely-inclined edges, which are designed to limit thethrow of the head and which When the head is in either extreme positionform a support for the head directly against the beam, and thus take thestrains from the friction-shoes.

From the above description it will be seen that in assembling the partson the beam the keeper members are fitted together one upon each side ofthe headand the head, with its keeper members, are slipped into positionuntil the flanges of said keeper aline with the rivet-opening in thebeam. A single rivet is all that is required to hold the keeper and itscarried head in position, and when in place the head is prevented fromlongitudinal movement. The head is well backed by the supporting-web 9,and the friction-shoes tend to hold the head in adjusted positions.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the'leastdeparting from the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

1. A brake-head for brake-beams having a recessedportion through whichthe brake beam isdesigned to pass, and friction-shoes on each side ofsaid recess; substantially as described.

2. A brake-head having a backing-fin de signed to transmit the strainspassing through the head; substantially as described.

3. A brake-head having a backing-fin, and friction-shoes; substantiallyas described.

49. A brake-head provided with a backingfin having double inclined facesfor cooperating with the beam, and concentrically-arrangedfriction-shoes; substantially as described.

5. The combination with a brake-beam, of keeper-plates, and a brake-headhaving friction-shoes cooperating With said keeper-plates; substantiallyas described.

6. The combination with a brake-beam, of keeper-plates, and a brake-headhaving concentrically-arranged friction-shoes cooperating with thekeeper-plates on each side of the brake-beam; substantially asdescribed.

7. The combination with a brake-beam, of

&

a keeper, a brake-head having concentric friction-shoes cooperating withsaid keeper, and a backing fin or web on said brake-head cooperatingwith the brake-beam; substantially as described.

In testimony whereof I hereunto afiix my signature, in the presence oftwo witnesses, this 5th day of January, 1905.

JOHN F. OCONNOR.
